Description
Technical field
The present invention relates to one kind be mainly used for aircraft, steamer, train and all using high-pressure oil pump, machining is high
The device of the grinding eccentric arc of pressure oil pump rotor sliding-vane.Especially processing on small slide plate has a bit of circular arc, large radius eccentric
Processing, can effectively ensure that processed slide plate it is contour and combination after concentricity requirement.
Background technique
The high-pressure oil pump for having been widely used for aerospace and several big pillar industries of national economy is to generate high-pressure and hydraulic
The critical component of oil pressure, and the processing of the slide plate in high-pressure oil pump is one of key technology and difficult point.Such as aircraft storage is answered
Accumulator in anxious energy etc. is that high pressure oil storage emergency energy is generated by high-pressure oil pump at work to realize emergency requirement
Measure accumulator in, the reliability of high-pressure oil pump is all crucial technical problem, directly affects oil pump performance, high-pressure oil pump is
One fuel tank internal and top are loaded on by the elements collection such as high-pressure gear pump, overflow valve, check valve, shut-off valve, pressure gauge, filter
It is formed.There is the rotor of slide plate to make rotary motion in cylinder, be mounted in cylinder to rotor eccentricity, slide plate is embedded in slot
's.Rotor is the cylindrical body with radial slot, places slide plate in slot, slide plate can be free to slide in slot.It is sliding when rotor rotates
Piece is tightly attached to pump inner cavity slide plate by the effect of centrifugal force or spring force (spring is placed on slot bottom) and is pressed to by the effect of centrifugal force
Cylinder inner wall, major defect are mechanical friction between slide plate and rotor, cylinder than more serious, thus generate biggish abrasion and
Energy loss.Rotor outer surface, cylinder inner wall and adjacent two slide plate form swept volume.As long as adjusting rotor to the bias of stator
Away from size, the flow of pump can be changed；The direction for changing eccentricity can change the direction of pump output liquid.Mainly as vertical
Formula motor group jacks up rotor and uses, while can also provide high pressure fuel source for other hydraulic devices.Modern designs require high-pressure oil pump
Small in size, light-weight, slide plate is installed in four slots of Slidine-vane rotor in high-pressure oil pump, and high-pressure oil pump at work, is opened
Under the influence of centrifugal force, slide plate contacts beginning slide plate with high-pressure oil pump shell inner hole wall, if slide plate is isocentric circular arc, with high pressure
The highest point of oil pump case inner hole wall contact is located at slide plate center, and the slide plate two sides contacted with high-pressure oil pump shell inner hole wall have
Gap, high pressure oil can generate the component for slide plate being pushed to Slidine-vane rotor slot bottom, slide plate and high-pressure oil pump in slide plate gap
The contact of shell inner hole wall cannot come into full contact with, and interior leakage increases, and consume energy, if spring is installed in Slidine-vane rotor slot bottom, narrow
In small space, the strength that little spring generates is not enough to offset high pressure oil component, if inclined-plane is processed into slide plate one end, although
The highest point for solving the problems, such as that slide plate is contacted with high-pressure oil pump shell inner hole wall is not located at slide plate center, but in certain pressure
Under, slide plate is not enough to come into full contact with high-pressure oil pump shell inner hole wall by centrifugal force, and interior leakage index does not still meet design and wants
It asks.If eccentric arc is processed into slide plate one end by experiment, Slidine-vane rotor is rotated in high-pressure oil pump shell high speed, slide plate
It can float up and down in four slots of Slidine-vane rotor, the highest point that slide plate is contacted with high-pressure oil pump shell inner hole wall is not located at slide plate
Center, while diplopia part in (Fig. 4) can be seen in slide plate, a vacuum section is generated, at this moment has a component instead cunning
Piece pushes high-pressure oil pump shell inner hole wall to, this is similar to generate lift with airplane wings, if concentricity and every after slide plate combination
A slide plate eccentricity can not meet design requirement, and four slide plates can generate the vacuum section of four different sizes, the handle of generation
Slide plate push to high-pressure oil pump shell inner hole wall component therefore it is also different, Slidine-vane rotor high-pressure oil pump shell high speed rotation under
Vibration can be gone out and hot-tempered sound increases, therefore, the processing of the key part slide plate in high-pressure oil pump is also difficult point, two work of slide plate
Surface roughness, flatness, depth of parallelism requirement are very high, and slide plate is after precision WEDM machine processing, by precision in previous processing
Grinding machine carries out fine grinding two sides again, slide plate low efficiency in precision WEDM machine work, and concentricity will depend on people after the slide plate combination processed
Work grinding guarantees that grinding efficiency is extremely low.
Summary of the invention
The object of the invention place in view of the shortcomings of the prior art, provides that a kind of structure is simple, the high height of grinding efficiency
Pressure oil pump rotor sliding-vane clamp, concentricity after the processing combination to solve key part slide plate, each slide plate eccentricity one
The problem of cause property.
It is of the present invention solve the problems, such as used by technical solution be: a kind of high-pressure oil pump rotor sliding-vane clamp, comprising: two
End face is formed with the step mandrel 1 of top centre bore, which is characterized in that the diagonal arc transition of rectangle is formed in the middle part of step mandrel 1
Non-cylinder, is formed with the accurate fastening grooves of embedded processed slide plate 2 on each diagonal circular arc, and when processing, housing screw 3 passes through
Processed slide plate 2 is pressed in accurate fastening grooves by the lateral fastener hole of accurate fastening grooves, is processed slide plate 2 and is fitted closely
On accurate fastening grooves working face.
The beneficial effect of the present invention compared with the prior art is,
Structure is simple, and grinding efficiency is high.The present invention is using the non-cylindrical for being formed with the diagonal arc transition of rectangle in the middle part of step mandrel 1
Body, and the embedded accurate fastening grooves for being processed slide plate 2 are made on each diagonal circular arc, constitute the processing group of key part slide plate
Tooling is closed, part is few, and structure is simple.Using 1 both ends center hole of step mandrel as benchmark, reference center's concentricity is in 0.001mm
In range, for top centre bore eccentricity within the scope of 0.001mm, accurate fastening grooves working face ensure that step mandrel 1
3 concentricity of processing slide plate, grinding circular arc and the eccentricity of step mandrel 1.It is this to replace the mating mode of underhand polish, improve mill
Cut efficiency, the slide plate concentricity, eccentricity after processing≤1 μm.
